I bought some of the LED replacements for Edison bulb incandescents, and
they have an afterglow that lasts for several minutes. It is very much
dimmer than when they are turned on, but is there none the less.

The speed isn't terribly surprising since the "phosphor" used is
actually a scintillator.
Unlike phosphors scintillators don't have long decay times so there
is no afterglow like that from a phosphor.
The IKEA LED lamp output may not be significantly modulated if the
wall wart constant current supply may have an output thats a little
smoother than just rectified AC.

Some white LEDs use phosphors, others use scintillators it varies from
manufacturer to manufacturer and part no to part no.
